Some expired bags of Fresh Express salad recalled

Fresh Express is recalling some 10-ounce Hearts of Romaine salads due to a possible risk of Listeria monocytogenes.

This is a precautionary recall after a random sampling test by the Food and Drug Administration found a single package of lettuce tested positive for Listeria monocytogenes, according to the company. No illnesses have been reported, and no other products are being recalled, the company said in a news release.

The recalled bags have already expired -- they have a use-by date of Aug. 23. Recalled bags feature a product code starting with G222 and a UPC code of 71279 26102 below the barcode, according to the company.
